由北京科技大学、邯郸市铸造厂、鞍山钢铁公司和河北机电学院共间承担的国家“七五”重点科技项目“稀土在灰铸铁中应用的研究”一连续铸造稀土灰铸铁管和砂型离心铸造稀土灰铸铁管的课题,经过共同努力,已圆满地完成了研制任务。此项成果对稀土在灰铸铁管中的作用和实际应用进行了较全面和系统的研究,对开发和利用我国富有的稀土资源和提高灰铸铁管的性能做出了较大的贡献并在理论方面有一定的创新,具有国际水平。
Research on the Application of Rare Earths in Gray Iron Casting, a key science and technology project undertaken by Beijing University of Science and Technology, Handan Casting Factory, Anshan Iron and Steel Co., Ltd. and Hebei Institute of Mechanical and Electrical Engineering, a “Seventh Five-Year Plan” key project, a continuous casting of rare earth gray cast iron pipe and sand centrifugal casting Rare-earth gray iron pipe project, through joint efforts, has successfully completed the development task. The results of a more comprehensive and systematic study of the role and practical application of rare earth in gray cast iron pipe made a greater contribution to the development and utilization of rich rare earth resources and improve the performance of gray cast iron pipe in theory There are some aspects of innovation, with international standards.
